GtkCombo::disable_activate

void disable_activate();

WARNING! This method has been deprecated in PHP-GTK 2
and should NOT be used in newly written code.

Stops the GtkCombo widget from showing the popup list when the
GtkEntry emits the "activate" signal, i.e.
when the Return key is pressed. This may be useful if, for example,
you want the Return key to close a dialog instead.
